UK: Woman killed, several injured in Westminster 'terror attack'

According to a BBC report, one police officer was killed in the nearby Houses of Parliament by an attacker.

"Several pedestrians were struck by a car on the bridge, before it crashed into railings," BBC report said.

Westminister Police said they are treating the gunshots outside as a terrorist attack.

One assailant was shot by police, a leader of House of Commons reportedly said.

Following the lock down in Parliament, Scottish Parliament has called the Referendum debate off.

The London Eye has stopped working.

Reports confirmed that Prime Minister of United Kingdom Theresa May is safe after the gunshot.

PM May will reportedly chair a meeting of the government's emergency Cobra committee later.

Meanwhile, Commander B J Harrington of Metropolitan Police while interacting with media said that the public safety is the first priority to them.

However the Commander could not confirm the actual number of casualties in the whole incident.

"We do not want to speculate the number of casualties" he said.

Commander also informed that additional officers will be on duty across London.

He also informed that Police Commissioner in-charge was present during the attack who has been treated as a witness.

People can dial 999 if they want to inform about anything that is suspicious and 1800789321 for giving any information related to the incident, Harrington said.
